CPT 93650Cardiology

Icar cath abltj av node func

CPT 93650 covers intracardiac catheter ablation of the AV node, a procedure where doctors use a catheter to intentionally disable the heart's electrical pathway between the upper and lower chambers. This is typically done to control rapid, irregular heartbeats that haven't responded to medication.

Billing tips

Always verify that diagnostic electrophysiology study codes (93600-93603) are not separately billable on the same date as 93650 unless medically distinct and documented
Impact: Prevents bundling denials that could reduce total reimbursement by $200-400
Document medical necessity by including failed medication trials (at least 2-3 antiarrhythmic drugs) and symptom severity in the pre-procedure note
Impact: Reduces medical necessity denials which account for 30-40% of 93650 claim rejections
When pacemaker implantation (33206-33208) is performed same-day, use modifier 59 on the pacemaker code and document that AV node ablation creates therapeutic necessity for pacing
Impact: Preserves full pacemaker reimbursement of $800-1200 that would otherwise bundle
Bill fluoroscopy separately with 76000 only if not included in your facility contract; most hospital-based EP labs include imaging in the global procedure
Impact: Avoid upcoding allegations; fluoroscopy is typically considered inherent to 93650
For Medicare patients, ensure ABN (Advanced Beneficiary Notice) is obtained if patient has not failed adequate medication trial, as LCD policies require documented drug failures
Impact: Shifts financial responsibility to patient for potential $551.51 denial rather than write-off
Code total procedure time and fluoroscopy time in procedure note; if sedation exceeds 30 minutes beyond induction, consider moderate sedation codes 99152-99153
Impact: Can add $100-150 in additional reimbursement for prolonged moderate sedation when appropriately documented

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 93650 in 2025?

The 2025 Medicare national average reimbursement for CPT 93650 is $551.51 for both facility and non-facility settings. This is based on 17.05 total RVUs (10.24 work RVU + 4.5 PE RVU + 2.31 MP RVU) multiplied by the 2025 conversion factor of 32.3465. Actual payment may vary by geographic locality.

Can you bill CPT 93650 and pacemaker insertion on the same day?

Yes, AV node ablation (93650) and permanent pacemaker insertion (33206-33208) are commonly billed together on the same date of service since the ablation creates therapeutic heart block requiring pacing. Use modifier 59 on the pacemaker code and clearly document that the ablation created the medical necessity for the pacemaker to prevent bundling denials.

What documentation is required to bill CPT 93650 for medical necessity?

Documentation must include the specific arrhythmia diagnosis, patient symptoms and their impact on quality of life, trials of at least 2-3 antiarrhythmic medications with documented failure or contraindications, consideration of alternative ablation approaches, and informed consent discussing the need for permanent pacing post-procedure. Many Medicare LCDs have specific drug trial requirements.

Is CPT 93650 a facility-only code?

While CPT 93650 is typically performed in facility settings (hospital inpatient, hospital outpatient, or ASC), it is not restricted to facilities only by Medicare. However, the 2025 rates are identical ($551.51) for both facility and non-facility settings, and the procedure's complexity and equipment requirements make non-facility performance extremely rare.

How many RVUs is CPT code 93650 worth?

CPT 93650 has a total of 17.05 RVUs in 2025, comprising 10.24 work RVUs, 4.5 practice expense RVUs (both facility and non-facility), and 2.31 malpractice RVUs. This makes it a relatively high-value procedure reflecting the technical skill and risk involved in intentional AV node ablation.

Can CPT 93650 be billed with a diagnostic EP study on the same day?

Generally no, diagnostic EP study codes (93600-93603) are bundled into 93650 when performed on the same day as part of the pre-ablation mapping and assessment. These can only be billed separately if performed for a completely distinct diagnostic purpose unrelated to the ablation, which is rare and requires exceptional documentation with modifier 59.

What is the difference between CPT 93650 and 93653?

CPT 93650 is specifically for ablation of AV node function, intentionally creating heart block to control ventricular rate. CPT 93653 is for ablation of atrial arrhythmias other than AV node (such as atrial flutter circuits or focal atrial tachycardia). Code 93653 has higher RVUs (20.18) reflecting greater complexity and is not intended to create heart block.
